Answer:
The answer is perpendicular to the base.
Step-by-step explanation:
600 + 300 + 150 + . . . is a geometric sequence with a = 600 and r = 1/2
Sn = a(1 - r^n)/(1 - r)
S5 = 600(1 - (1/2)^5)/(1 - 1/2) = 600(1 - 1/32)/(1/2) = 1,200(31/32) = 1,162.5
Sorry i wish i knew the answer i’m actually learning that in class but i don’t quite understand it
Answer:
The skid distance to be used is 54 feet.
Step-by-step explanation:
Given:
Four skid marks on the highway.
in feet.
We have to find the skid distance.
The skid distance that will be used to further calculate the skid speed is actually the mean skid distance.
Mean skid distance (m) :
⇒
⇒
⇒
⇒ feet.
So the skid distance to be used is 54 feet.
